Linux Plesk 8.6 to Linux Plesk 10.2 errors

[CsabaA]

I am trying to migrate a few domains from linux plesk 8.6 to linux plesk 10.2.

When executing
/usr/local/psa/bin/pre9-backup-convert -v convert -d /var/lib/psa/dumps/ szentimrebackup
I get the following error:
Runtime error: 'NoneType' object has no attribute 'getGuid'

Tried uploading to the server backup repository, the gui gives the following error:
Error: FTP dump file does not exists

and examining the PMM log file, states the same as previous:
[12:13:22|INFO: 1190.log] Executing utility: /usr/local/psa/bin/pre9-backup-convert convert --timestamp=1111041213 --directory=/var/lib/psa/dumps /tmp/php49BBQe
[12:13:22|INFO: 1190.log] The utility executed with the return code 1
[12:13:22|INFO: 1190.log] The return code was
No output on STDOUT were performed by the utility
The output on STDERR was:

[12:13:22|INFO: 1190.log] pmm-ras finished. Exit code: 127

How can I proceed to import the backup from plesk 8.6?

Looks like some database inconsistency. It is required detailed investigation directly on your servers, therefore contact support team would be better solution.
